中文摘要：
在考虑悬置扭转刚度的条件下,为带防扭拉杆的动力总成悬置系统建立了包括拉杆模型在内的动力总成-拉杆系统计算模型。利用该模型,计算了一实际的动力总成悬置系统中动力总成的位移、悬置的位移和力。结果表明,在动力总成承受大转矩或碰撞的工况下,采用实际的拉杆模型（两点模型）能得到更准确的计算结果。
英文摘要：
With consideration of the torsional stiffness of mounts, a calculation model of powertrain-torque strut system, including torque strut model is established for powertrain mounting system with torque strut. Then the displacements of powertrain and the displacements and forces of mounts in a real powertrain mounting system are calculated. The results show that in the working conditions of powertrain subjected to high torque or crash, the cal- culation using practical torque strut model （two-point model） can get more accurate results.
